Let's divide 75716577 by 3
The aim is to understand the frequency of 3 in 75716577.

On to step 1:
7 divided by 3 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 6 from 7 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Step 2:
The number 3 fits into 15 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 15 from 15 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Advancing to step 3:
3 goes into 7 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Deduct 6 from 7 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Moving on to step 4:
The number 3 fits into 11 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2523.0
Subtracting 9 from 11 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

On to step 5:
When dividing 26 by 3, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 25238.0
If we take 24 away from 26, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

On to step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 252388.0
Subtract 24 from 25 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Advancing to step 7:
3 goes into 17 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 2523885.0
If we subtract 15 from 17, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Moving on to step 8:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 25238859.0
Subtract 27 from 27 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25238859.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25238859.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 25238859.0 with a remainder of 0.0.
